Deuteronomy 6:4-9

“Hear, O Israel: The Lord our God is one Lord: and thou shalt love the Lord thy God with all thine heart, and with all thine soul, and with all thy might. And these words, which I command thee this day, shall be in thine heart: And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sitterst in thine house, and when thou walkest by thy way, and when thou liest down, and when thou risest up. And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes. And thou shalt write them upon the posts of thy house, and on thy gates.”

This is known as the “Jewish Prayer Shema Yisrael”

In the Jewish tradition, these are the verses that are written on a scroll inside a “Mezuza” which is then placed on the doorpost of one’s home.

The Catechism of the Catholic Church states it this way:

“The Life of Man-To Know and Love God”

“God, infinitely perfect and blessed in Himself, in a plan of sheer goodness freely created man (humans) to make him share in His own blessed life.  For this reason, at every time and in every place, God draws close to man.  He calls man to seek Him, to know Him, to love Him with all his strength.”
